Application filed May 12, 1917, Serial No. 168,194.

To all whom it mag concern:

Be it known that I, EUGENE FRANK SCHOELL, acitizen of the United States, re. siding at New Britain, in the county of Hartford and State of Connecticut,have invented certain new i and useful. Improve ments in Curtain-Fasteners, of which the following is a specification.

My invention relates to improvements in curtain fasteners, oflthe type for holding curtains of automobiles and other vehicles and the object of my improvement is to produce a curtain fastener in which theetud member is formed of a pair of cooperating spring members that are held in place by the resiliency of the. material of which it is made and that is made of asingle piece of. strip, sheet material. a 1n the accompanying drawing Figure 1 is a plan view of my improve curtain fastener with adjacent parts of our.- tain to which the same is applied.

Fig. 2 is a similar View on an enlarged scale of the curtain fastener shown inFig. 1. Fig. 3 is a similar View of the eye or socket member. b Fig. 4 is a similar view of the studmem- Fig. 5 is a plan view of the blank for the stud member.

Fi 6 is a sectional view on the line 00 m of Fig. 1.

Fig. 7

is a similar view with the opposing arms of the stud members in the closed position for being released by engagement with the socket member.

My improved curtain fastener comprises a socket member 10 for being secured to one of the curtains or other devices to be fastened together, such as the curtain 11, and provided with a hole 12 in the middle portion for receiving the other member of the curtain fastener, and the said other member 13 is in the form of a stud member that is secured to the framework and the same is provided with means for engaging with the hole 12 in the socket member 10 to be described.

The socket member 10 is composed of a pair of mating plates for being positioned, one on each side of the curtain 11, and held together by lugs or prongs 14: that are integral with one of the plates, extend through the material of the curtain 11, and

are bent over against the outer face of the otherplate.

As shown, the outer. plate 15 is positioned on the outer face of the curtain 11, has a set of four lugs orprongs 16. distributed around the periphery that penetrate the material of the curtain 11, and has the hole 12 atfithe middle. The inner plate 17 is positioned at the rear or inner face of the curtain 11,; has notches 18 in. the peripheral edge that register with and; receive the prongs 14, and has an opening 19 in the middle portion.

The ends of the prongs 1 1 are bent over against the inner face of the inner plate 17.

The plates 15 and 17 are made of sheet material and the hole 12 in the outer plate 15 serves as the socket member proper, the opposed edge portions 20 on two sides serving as the engaging or looking members for cooperating with the stud member 13. The opening 19 "n the inner plate 17 is appreciably larger than the socket hole 12 in the outer plate .15 suitably to provide clearance for the stud member 13.

The stud member 13 is formed from a single piece of sheet material in strip form,

the middle portion 21 being straight for an appreciable length to form the base, the material being bent back by a return bend 22 at the ends of the base 21 and extending along inwardly to provide reinforcing members 23 for the end portions of the base 21 and at the inner, opposed ends of the reinforcing members 23 are outwardly extending branches 24: that are directed generally at a right angle to the base 21 and that serve as spring arms and cooperate suitably to serve as the stud proper, in engagement with the socket member 10.

The spring arms 24: are positioned in spaced relation so as to be a snug fit in the socket hole 12 in the socket member 10, and are provided with engaging members 25 for engaging with the opposed edge portions 20 of the socket hole 12.

The said engaging members 25 are in the form of lugs formed integral with the arms by slitting the material at the lower edge 26 of the lug and indenting the material outwardly above the slit. These lugs therefore are rigid per se. Thus the lugs 25 have an abrupt lower edge 26, suitable for locking against the cooperating edge portions 20 of the socket hole 12, and

the outer faces 27 are inclined, suitably to provide converging sliding surfaces that facilitate bringing the partsinto engagement.

The base 21 is provided With holes 28 for holding screws by which the stud member 13 is secured to the woodwork or other supporting device.

he parts are brought into engaging position by slipping the socket member over the arms of the stud member, the edges of the socket hole engaging with the lugs 25 and forcing the arms 24 together momentarily, and after the socket member is brought below the holding edges 26 the arms will spring back to the holding position.

F or releasing the parts the ends of the arms 24 are squeezed together until the socket member can be slipped over the lugs.

As. shown the arms 24: are appreciably concaved and the active edges 20 of the socket hole 12 are formed to correspond. It is understood other shapesfor these parts may be used than those shown.

I claim as my invention 1. A curtain fastener, comprising a socket member of sheet material, having means for securing it to a curtain and provided with a stud-engaging hole, and a stud member formed of a single piece of strip sheet material, having a mlddle portion adapted to serve as a base, and reinforcing end portions overlying the base :and extending toward one another and terminating in a Copies of this patent may be obtained for five cents each, by addressing the .With an outwardly abrupt lower edge tion of the socket pair of cooperating spring arms arranged in spaced relation and adapted to be entered in the socket hole, each arm provided directed lug having an to engage the edge porhole.

2. In a curtain fastener, a socket member having an opening for receiving a stud member, and a stud member for V with said socket member, said stud member formed of a single piece of strip sheet material with its middle portion serving as a base and having reinforcing end portions formed by return bends at the ends of said base, the ends of said return bends extending outwardly in parallelism and in spaced relation and'supported by the return bends, said ends provided with cooperating out wardly directed rigid lugs for engaging the socket member.

3. A stud member for curtain fasteners, formed of a single piece of strip sheet material, and comprising a socket-engaging portion in the form of a pair of spring arms arranged in spaced-relation and having lugs on'their outer faces made with abrupt locking'edges, a base adaptedito be engaged with a support for the stud member, and connecting parts interposed between said base and arms and uniting them.
